' To all whom it may concern."

' Be it known that LTHOMAS S. ABERNATHY, a citizen of the-United Statesof America residing at' Birmingham, in the county of Jefferson and Stateof Alabama, have'invented certain new and useful Improvements inRazor-Blade Knives, of which the following is a specification.

My invention relates to a razor blade knife consisting ofa novel type ofknife handle or holder by which any standard t pe of safetyrazor'blade-is held so as to orm a knife suitable for many domesticpurposes, such as ripping or cutting cloth, paper, corns, or for lighthousehold work requiring a keen sharp blade.

My invention is more particularly concerned with the construction of avery chea and simple safety razorbladeholding kni e handle whichconsists preferably of a stamped metal handle having a blade supportingend provided with a stud and a notch, and a spring blade clamp adaptedtov interlock with the handle slot through the end slot of the razorblade and to be held by a keeper on the handle so as to interlock theblade with the stud. I thus form a very light and inexpensive stampedmetal article by means of which discarded razor blades can be utilizedwhich would otherwise be thrown away.

I have illustrated what I regard as the referred embodiment only of myinvention in the accompanying drawings which form a part of thisspecification, and in which Figures 1 and 2 are plan and side elevationsrespectively of the handle ortion.

Figs. 3 and 4: are Ian and si e elevations respectively of the b adeclamp.

Fig. 5 is a plan view of the razor blade knife showing the razor bladeclamped in position.

Similar reference numerals refer to similar parts throughout thedrawings.

As illustrated, my invention comprises a handle portion preferablyformed of stamped sheet metal and provided with a handle shaped end 1and a blade supporting end 2, the latter being provided with a slot 3.punched in its outer end and a boss or stud 4 raised near its .innerend. The handle is flared to provide rounded guard portions 5 which areoverlapped by the inner end of the razor blade 6 and which have -a widthSpecification of Letters Patent.

slightly greater than the width of the blade to form a protection forthe hand. The ham-- dle-is provided with a keeper 7 stamped up from itsbody portion.

The blade clamp 8 is preferably in the fornr of a narrow strip ofstamped metal provided at one end with a tongue or lip 9 which isconnected to the clamp by a short right angled neck portion 10. Theclamp preferably has a slight curve lengthwise thereof and terminates atone end in a tip or point 11 adapted to engage and seat in a grooveformed in the overhung end of the keeper 7. For the purpose ofreinforcing the blade the clamp is provided with enlarged portions 12and 13 near its ends, its main body portion being just wide enough tocover and conceal the usual slots or openings 14 and 15 formed in therazor blade as illustrated, though it is understood that this blade mayhave more than two slots or a single elongated slot.

In'operation, the razor blade 6 is laid on the handle end 2 and thetongue 9 of the clamp is inserted through the end hole 14 of the bladeand through the slot 3 in the handle portion with its convex surfacenext to the blade; The stud 4 is then caused to engage in the blade slot15 and the rear end producing a razor blade knife which can be veryinexpensively produced and which will serve many useful purposes. a

While it is preferable that the stud 4 should be formed on the handle itis within the contemplation of my invention that the co-acting parts ofthe knife handle shall be provided with any suitable means to interlockwith the blade at its end neXtto the handle when clamped in operatingposition. This invention is not intended to be restricted in scope tothe specific embodiments shown, but contemplates such modifications ascome within the spirit and scope of the claims.

' razor blade,'the slot being near the outer end of the support, afastening member having a depressed tongue adapted to pass through theregistering openings in the blade and its support, and means to securethe other end of said fastener to the handle with the body of thefastening member spring to clasp the blade to its support, the handlehaving its end adjacent to the blade wide enough to form an end guardfor the cutting edges of the blade. 1

2. In a razor blade knife handle, a'stamped metal plate having a keeperstruck up from" its handle end and having a stud struck up from itsblade supporting end, there being a slot in the outer portion of saidlatter end, said stud and slot being in position to register withopenings in a safety razor blade, and a blade clamping member having anoffset depressed tongue adapted to pass through the handle slot andhaving a curved body portion adapted to overlie said stud and at itsrear end to be sprung 1nto engagement with said keeper, substantially asdescribed.

3. In a knif handle for safety razor blades, a stamped metal handlehaving a relatively narrow blade supporting end, the handle being madeWider at its point of juncture with the blade supportin end thanthewidthof the safety razor bla e to be mounted thereon, said bladesupporting end having a slot near its; end remote from the handle, aclamp member having a tongue adapted to be inserted through a slot inthe razor blade and through said slot in said blade supporting end ofthe handle, a stud on the blade supporting end near the handle adaptedto engage in a slot in the safety razor blade, and a keeper on thehandleto engage the free end of the clamp and hold it in razor bladeengaging positlon on the handle,

' substantially as described.

In testimony whereof I afiix my signature.
